Of course I know that, but authentication remains the #1 security application
except for payments and here there are still no visible discussions at all.

IMO, if the outcome (whatever it is), "can't pay", then it is toast.

We can't just throw away the fundamental security model that billions of users and deployed applications depend on, and I see no evidence (at least in these few slides) that such issues have been considered by this proposal.
